Vulnerability Overview

The Masteriyo - LMS for WordPress plugin is vulnerable to Sensitive Information Exposure in versions up to, and including, 1.6.7 via the 'get_item' REST callback. This can allow authenticated attackers to extract sensitive data including user metadata.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Masteriyo LMS < 1.6.8 carries this weakness at get_item, and reaching it takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Masteriyo LMS the fix is 1.6.8: builds < 1.6.8 are affected, anything from 1.6.8 onward is not.

Remediation

Update to version 1.6.8, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Masteriyo LMS 1.6.8 closes this, and updating the plugin is the step that ends it.
